I-BA1404 iyi-low-voltage, idizayini yamandla aphansi esebenzisa amandla amakhulu angu-500mW.
Ihlanganisa ukushintshashintsha kwe-stereo, ukushintshashintsha kwe-FM, nokukhulisa imvamisa yomsakazo ku-chip eyodwa; idinga izingxenye ezimbalwa ze-peripheral;
Ukuhlukaniswa kweziteshi ezimbili kuphezulu, ngenani elijwayelekile elingu-45dB;
I-impedance yokokufaka ngu-540Ω (fin=1kHz), futhi inzuzo yokufaka ingu-37dB (Vin=0.5mV);
Ukukhishwa kwe-RF kungafinyelela ku-600mV.
Isekhethi isebenzisa umdwebo wakudala kakhulu, futhi ukukhulisa ukushuna kwengezwa kokuphumayo ngemuva ukuze kuhlangatshezwane nezidingo zamandla. Ukunakekelwa kufanele kuthathwe lapha kumjikelezo wesithumeli ukuze kungabi namandla amaningi. Akukho emthethweni uma inkulu kakhulu futhi ithinta amanye amafrikhwensi. Amandla aphezulu asemthethweni kuphela kwamanye amabhendi efrikhwensi. Ngangingawuqondi umthetho lapha, futhi amandla ngaleso sikhathi ayephakeme ngokuvamile.
Isiteji sangaphambi kwesiteji se-stereo iyisikhulisi somsindo samashaneli amabili. Uma okokufaka kungu-0.5mV, inzuzo iphezulu njengo-37dB kanye nomkhawulokudonsa wefrikhwensi ngu-19kHz.
Ngangesaba ukuthi amandla okukhipha angu-1404 ayenganele, ngakho-ke ngengeza okunye ukukhuliswa kamuva.
I-inductor eqondile esithombeni esingenhla iyalungiseka. Ngokuyishintsha, ishintsha imvamisa ye-resonance, okuyimvamisa yokuphela kokuphumayo. Ingabalwa ngokusekelwe kufomula. Kodwa i-inductance ayizange ibalwe ngaleso sikhathi. Ngakho vele uvule futhi usebenzise umsakazo ukuze wamukele. Lungisa imvamisa yokwamukela umsakazo uma ulungisa. Inqobo nje uma umsindo engiwukhiphayo ulungile. Umphumela we-pop-up muhle kakhulu. Ngaphezu kwalokho, kubalulekile ukunaka imingcele ye-capacitor lapha, futhi imingcele ekukhuliseni okulandelayo kanye nezinkomba zokulungisa idinga ukulungiswa isinyathelo ngesinyathelo. Kumelwe ukuba kwathatha isikhathi. Ngokuvamile, umsindo owamukelwe ucacile.
